Title:
When REBUILDING from UEFI to non-UEFI instance ends up in ERROR state
Status in OpenStack Compute (nova):
Incomplete
Bug description:
If an UEFI instance is REBUILDED using a non-UEFI image as a
replacement via e.g.:
# openstack server create --flavor c4.2xlarge --image
ubuntu-22.04-x86_64-uefi --network mynetwork --key-name mykey ubuntu-
uefi-test --security-group default
# openstack server rebuild --image ubuntu-22.04-x86_64 ubuntu-uefi-
test
The instance ends up in an error state:
```

libvirt.libvirtError: Requested operation is not valid: cannot undefine
domain with nvram
```
Additionally the instance cannot be deleted. Only manually by issuing
a ``virsh undefine [instance_uuid] --nvram``
I am pretty certain this is related to
https://github.com/openstack/nova/commit/539d381434ccadcdc3f5d58c2705c35558a3a065
which introduced the deletion of nvram if the machine supports UEFI. Likely
this info is lost on the switch to the non-UEFI image and therefore this flag
is not set.
I am wondering why this flag is not send to libvirt by default to always be
able to delete instances UEFI or not?
